9 Claims. (Cl. 24258) This invention relates to improvements in a mountfor heavy 'web rolls adapted to receive and support the rolls inselected positions sequentially to be unwound and fed to adjacentprocessing machinery.

In the usual practice of manufacturing corrugated paper board, paper plyboard, and other stock made up from rolls of web, processing machineryof various types suitable for current needs are employed which aresupplied with material from the web rolls.

An object of the instant invention is to afford a mount for supportingand moving heavy web rolls sequentially in selected positions while therolls are unwound and the web supplied to processing machinery disposedadjacent the mount.

Another object of the invention is to construct a web roll supportingmount having adjustable stands oppositely disposed upon a base that ismovably positioned on a relatively stationary situs, so the mountincluding the base together with a web roll supported by the stands isbodily movable into selected positions for unwinding of the roll andfeeding of the web to adjacent processing machinery.

And a further object of the invention is to afford a power activatedappliance for the reception and support of heavy web rolls in selectedpositions for unwinding, that is conveniently manipulated by a singleoperator.

Other objects and advantages of the invention appear in the followingdescription.

An illustrative embodiment of the invention is shown in the accompanyingdrawings, in which:

Fig. 6 is a front elevational view of the base and its floor support,including an adjusting device for the base;

Fig. 7 is a rear end elevational view of the base and its floor supportincluding a pivot upon which the base swings; I

Fig. 8 is anelevational view of the base and its support in section onthe line 8 8 of Fig. 2;

Fig. 9 is an elevational viewpartly in section showing the controllingmechanism for the hydraulically operated brakes used in the apparatus;and p p I Fig. 10 is a diagram showing-the electrical connections andcontrols for the motors that activate the stands.

The illustrative embodiment of the invention consists of an apparatus inwhich is included two similar stands, indicated'generally by 'A and Brespectively mounted upon a common base "11 of rectangular formpreferably made of channel iron and di'spos'edmovably' on theanchorplates 12'and 12 (Figs.- *1, 2, 6, 7, andS) that are secured inplace upon the floor 1.3.

The stands A:and'B 'eachare supported upon the base by wheels14 mountedupon brackets 15 that project downwardly from the corresponding standsat'the sides thereof and overlap the base. The wheels travel on thelowermost flanges (serving as longitudinally extending guiderails) ofthe channel iron base and serve to guide longitudinal movement of thestands thereon. In this manner the stands are maintained constantlyalined with each other.

The stands A and 'B are adjustably moved on the base 11 toward and fromeach other by means of individual propelling mechanisms located in thestands, each propelling mechanism consisting of a reversible motor 16-16operatively connected with a companion reducinggear 1717 that has achain and sprocket connection 18'18 with a counte'rsha'ft 19-1 9" thatis supported in bearings 20 beneath the corresponding stand and travelstherewith. In this manner traction of the stands 'on'the base isafforded. On the ends of the counte'rshaft 19 (Figs. 1 and 5) aresplinedpinions2l that mesh with corresponding rack-bars 22 secured tothe base 11 adjacent the top thereof, so that movement of the standslengthwise of the base in one direction or the other occurs accordinglyas the countershafts are rotated.

The base ll'has a series of transverse bars 23 secured on its bottom,the ends o'f which extend'loosely through corresponding stirrups 24 onthe anchor-plates. The bars extend loosely through said stirrups so asto permit lateral swinging movement of th'e'base 11 about a pivot 25that projects upwardly from the rear-most anchor-plate 12 The base isadjustably moved on the anchor-plates by means of mechanism (Figs. 1, 2and 6) consistingof a pinion 26 mounted on a stud 27 that projects fromthe front end of the base Hand is provided with a head 28 and a handle29 by which the pinion is turned-about the axis of the stud] The pinion26 has meshing engagement with a rack 30 that is mounted on the foremostanchor-plate 12 so that lateral swinging movement is imparted to thebase 11 accordingly as the handle 29 is manipulated in turning thepinion 26. By this means the base 11 and both stands A and B are bodilyswung laterally over the anchor-plates'for the purpose hereinafterdescribed.

Upon the top of each stand (Figs. 1, 2 and 9) is positioned a mount 31having a horizontal spindle 32 provided on one end thereof with acentering chuck 33, the chucks being disposed in axial alinementpermanently with each other and oppositely disposed.

The particular construction of the chucks is immaterial to the inventionas any type of chuck may be employed that is suitable to support a webroll 34 whenthe chucks are inserted into and fit the bore of the roll.The spindles 32 for said chucks each have in connection therewith abrake mechanism (Fig. 9), indicated generally by C, preferably of a typeoperated hydraulically in the usual manner. Each brake mechanism C isprovided with a liquid feed pipe 35 that has connection with a liquidpressure generator, indicated generally by D, that is secured on theforemost stand A and provided with a handwheel 37 for manipulatingit."This generator is of any suitable type adapted to vary the pressuresupplied to or withdrawn from the feedpipes 35 accordingly as thehand-wheel 37 is manipulated. The feed pipes 35 are coupled together bymeans of'a'fiexible conduit 38 whereby the pressure in both hydraulicmechanisms C is raised or lowered alike. The conduit has formed thereinan expansion loop 39 by which is permitted relative movement of thestands A and'B without interference with the flow of oil in the feedpipes 35. In connection with the generator D is arranged apressuregauge' 40 by which to observe the amount of pressure supplied tothe brake mechanisms. 7

The purpose-of thebrake mechanisms C and generator D is to controlrotation of the Web roll'as it isunwound and especially to preventracing of the roll and to control the tension of the web as it issupplied to an adjacent processing apparatus (not shown).

The construction of the hydraulic brake mechanism C and the generator Dhere shown and described (Fig. 9) is exemplary, Each brake mechanism hasan hydraulic jack cylinder 36 mounted on a yoke 41 that extends up fromthe mount 31 astride a brake-shoe 42 forming part of the brake mechanismC. The brake shoe has a friction lining 43 that bears against abrake-drum 44 splined on the chuck spindle 32, and a plunger 45 in thejack cylinder is operatively connected with the brake shoe, so that whenliquid pressure is applied through the feed pipe 35 to the jack cylinderthe brake mechanism is activated.

The generator D is mounted on the adjacent mount 31 and has a cylinder46 connected with the feed pipes 35 and provided with a piston 47 andjack screw 48 for activating the piston. The cylinder 46 is filled withliquid which is forced into the feed pipes with more or less pressurewhen the jack-screw is turned upon manipulation of the hand-wheel 37. Inthis manner the brake mechanisms are applied with more or less force andunwinding of the web roll tensioned accordingly.

As exemplified in the diagram (Fig. 10) the motors 16 and 16' areenergized by current from a suitable source (not shown) by conductors,indicated generally by B, through which current is supplied to the motor16 by an intermediate group of circuit wires, indicated generally by F,and to the motor 16' through another group of circuit wires, indicatedgenerally by G. The energizing current is controlled by a group of pushbutton switches 50, 51, 52, 53, 54, 55 and 56, there beingsolenoid-operated switches 57 appropriately connected with the groups ofcircuit wires F and G respectively.

Preferably, the push button switches 50 to 54 inclusive are groupedtogether and positioned on the foremost stand A and exposed to theexterior thereof within easy reach of the operator, and the other pushbutton switches 55 and 56 are similarly located on the stand B and usedby the operator to supplement push button switches in the former groupwhen the operator is located in that vicinity.

In the diagram the push button switches are arranged with the otherelectrical connections so that closing the switch 51 is accompanied byrotation of both motors 16 and 16 in the same direction causing travelof both stands A and B forwardly upon the base, and when the push buttonswitch 50 is closed the action of the motors is reversed causing thestands both to travel rearwardly on the base. Upon closing the pushbutton switch 53 both stands A and B are moved toward each other uponthe base, and closing the push button switch 52 causes movement of thestands on the base apart from each other. The push button switch 54 isarranged to cause resetting of the electrical apparatus as in the usualpractice. The switches 55 and 56 are supplemental to the switches 52 and53 by which the operator is enabled when located at either end of themount to jockey the stands forwardly or backwardly on the base in orderto perfect alinement of the web with the processing appa ratus locatedadjacent the mount.

Operation In using the invention the stands A and B are initially setapart from each other on the base 11 to permit insertion of a web roll34 between the centering chucks 33 which is readily accomplished bymomentarily closing the push button switch 52. The web roll is thenmoved into position between the centering chucks in alinement therewithby use of any suitable hoisting or elevating appliance (not shown),following which the stands are moved toward each other on the base,readily accomplished by closing the push button switch 53. By thisaction the centering chucks are driven into the bore of the web roll inreadiness for the unwinding operation.

In order to prevent buckling of the Web as it is drawn into a processingapparatus placed adjacent the mount the angularity of the base 11 isadjustably shifted upon the anchor plates 12 as is necessary toestablish proper parallelism between the mount and the opposing webrecciving end of said processing apparatus, this adjustment being madeby manipulating the handle 29 to cause swing of the base upon its pivot25. To assure correct alinement of the web roll with respect to theprocessing apparatus, the stands A and B together with the web rollmounted thereon are jockeyed forwardly or backwardly on the base 11 byselectively manipulating the push buttcn switches 50 and 51.

It is desirable that tension of the web as it is unwound from the rolland drawn into the processing apparatus be maintained with more or lessuniformity, and this is accomplished by manipulation of the hand wheel37 by which the liquid pressure generator D is operated and the brakemechanism C controlled whereby resistance to unwinding of the roll to aproper extent as to sustain the required tension of the web is affected.
